Internet of things ( IoT) is the Internet where everything is connected. The Internet of Things is essentially the Internet. It is a network that extends and expands on the basis of the Internet. It combines various information sensing devices through the network to realize the interconnection of people, machines, and things at any time, anywhere.
The Internet of Things is also called pan-interconnection in the IT industry, that is, the Internet of Everything.
The real definition of the Internet of Things is to connect various items to the Internet through information sensing equipment such as radio frequency identification, infrared sensors, global positioning systems, laser scanners, etc. intelligent identification, positioning, tracking, monitoring, and management.
The Internet of Things was first proposed by Microsoft President Bill Gates. In 1995, Bill Gates said in the book The Road to the Future that the future network is not limited to computers and portable devices, but may also include items, that is, the concept of the Internet of Things.
The realization of the Internet of Things involves many technologies, among which key technologies include radio frequency identification technology, sensor network, M2M system framework, and cloud computing. The following only briefly introduces RFID technology and cloud computing:
1. RFID Technology
Radiofrequency identification technology, that is, radio frequency identification, or RFID for short, is a simple wireless system that includes three parts: reader, tag, and application. Mainly tags, tags are composed of coupling elements and chips, each tag has a unique identification code, and then attached to the object, and then communicates with the reader through the antenna, and the reader transmits the collected information to the application for calculation. So as to give the object the function of speaking.
2. Cloud Computing
Cloud computing is to aggregate multiple relatively low-cost computing entities into a multi-super virtual computer with powerful computing power through the network. With the help of cloud computing, users can simplify their terminal into a simple input and output device.
Then enjoy the powerful processing power of cloud supercomputers according to their needs. Because the IoT perception network acquires a large amount of data information after the information is transmitted to the network. It enters the cloud platform, and then the cloud supercomputer performs nanosecond processing to build a real real-time IoT world.
The application field of the Internet of Things involves all aspects of life, such as intelligent transportation ECT, and smart home.
Especially the intelligent transportation ECT, which is currently the Internet of Things that can physically sense to the end. Compared with the old parking card, the card can be handed over in steps, and it is much faster and more convenient to charge without parking.
There are also smart homes. The current application is not particularly popular. First, the cost of whole house intelligence is relatively high, and second, the demand for this aspect is not very strong. When the whole society is talking about the Internet of Things, then the smart home is standard. The above is the general content of IoT (Internet of Things).
